The backend destroy signal is emitted before the output_remove
signal is. When the destroy signal is emitted listeners remove
their output_remove listener, so the output_remove signal is never
received and listeners have an invalid output pointer.
The correct way to solve this would be to remove the output_remove
signal completely and use the wlr_output.events.destroy signal
instead. This isn't yet possible because wl_signal_emit is unsafe
and listeners cannot be removed in listeners.
keymap_size is a size_t. Otherwise the build fails on arm like
../types/wlr_keyboard.c: In function 'wlr_keyboard_set_keymap':
../include/wlr/util/log.h:34:17: error: format '%lu' expects argument of type 'long unsigned int', but argument 5 has type 'size_t {aka unsigned int}' [-Werror=format=]
_wlr_log(verb, "[%s:%d] " fmt, _strip_path(__FILE__), __LINE__, ##__VA_ARGS__)

This backports some changes to #319 to fix the screenshooter data
format. This also adds wlr_backend_get_renderer which will be
useful to support multiple renderers.
This decouples wlr_output_enable and the wl_global.
The previously internal functions wlr_output_(destroy/create)_global are
exposed and used automatically in the wlr_output_layout to create/tear
down the global.
The compositor can handle them itself if it wants to, but I think this
is the right moment to create/destroy the wl_output when the
wlr_output_layout is used.
This adds back `wlr_output::needs_swap`. This allows a backend to
request buffer swaps even if the output isn't damaged. This is
needed by the DRM backend to trigger pageflips when the cursor
moves.
